Specification of Letters Patent. 7 Patented D c, 2, 1919.

Application filed December 17, 1918. Serial No. 287,215.

To all whom it may concern:

Be it known that I, SUMPTER L. HARwooD,

a citizen of the United States, and a resident,

of Uniontown, in the county of Perry and the body 10 and is beaded as at19 for con i and turns free of the disk 17 except at its central portionadjacent to the screw. Atthe periphery. the disk 17 extends beyond Stateof Alabama, have invented a new and venient grasping. The topof the body10 Improved Shaving-Cup, of which the following is a description.

My invention relates to a shavin cup and has for its general object toprovi' e a shaving cup adapted to accommodate aninsertible cartridgecontaining shaving cream and with a fountain thereon together with means,to discharge the desired quantities of the cream into the fountain.

The above and other objects as well as the advantages .of my improvedconstruction will be explained in the specific descrlption following. I

Reference is to be hadto the accompany-. ing'drawing forming a part ofthis speclfication it bein understood thatthe draw- 7 ing is merelyilustr'ative of one example of the invention.

Fig. 4 is a longitudinal vertical section as indicated by the line M,Fig. 5.

Fig. 5 is a cross section taken through the line m-m, Fig. 4;

Fig. 7 is a plan view of the top or cap of the interchangeable cartride;

Fig. 8 is a plan view of t e piston;

Fig. 9 is a fragmentary vertical section of parts of the up er portionof the shaving cup taken in a p ane corresponding with'the line 'ww,Fig. 4.

In carrying out my invention a cylindrical casing 10 is provided, havinga permanent bottom 11 havin a flange 12 suitably fastened to the b y 10at the lower edge. The bottom 11 has a depression 13 and is perforatedcentrally of the depression to receive the unthreaded portion 14 of ascrew 15 disposed axially in the body. Longitudinal movement of thescrew is prevented by a collar 16 thereon in the depression 13 at theinterior of the bottom 11 and operating disk 17 at the exterior of saidbottom for turning said screw with which the .o erating disk'is rigid.Said operating dis has a depression corresponding with the depressedcentral portion of the bottom 11 and formed at the edge 23 U-sha ed incross section to fit overltheedge of t e body of the cartridge. Thebottom of the cartrid e 22 consists of a piston 24 which when t ecartridge is in place is adapted to be actuated by the screw 1'5 forextru'din the shav- I he Pi on ingcneani from the nozzle 21. 24 1S.1n1t1a.lly slightly larger in diameter than the internal diameter ofthe cartridge 22 and hasa'fluid-tightfit in the latter owing to theelasticity ofthe carton which may be formed of paper, the fluid tightfit being atf tained without the use of piston ringsand by forming theedge 25 of the piston semi circular in cross section to present a smoothinterior surface to the cartridge and snugly engage the same. *Atthecenter the piston 24 is cupped as at 26 and perforated. The walls atthe perforation are tinnedjand a nut 27 is cast in position from Babbittmetal, the threads being cast at the same time. In practice when thecartridge is made up the piston 24:- constitutes the bottom thereof. Apiece of tinfoilor the like is pasted over the nut so as to form a'seal,but the seal may readily be punctured by the screw 15. For placing thecartridge in the casing 10 the cap 20 is removed and the nut 27 iscaused to engage the threads of the screw 15 and the cartridge with itspiston or bottom 24 turned until the cartridge is fully entered in thecasing, resting against the bottom 11 after which the cap 20 is replacedso that the nozzle 21 of the cartridge will project therethrough.

A combined bowl and valve is employed' 65 3 1 formed on .acap 23 securedto the. cartridge top of the nozzle 21, the latte-r having a dischargeorifice 33 centrally therein at the to bo vl 291 may be screwed tightlyonto the nozzle 21 so that the valve 32 will close the 'dischar eorifice 33 whereas a slight turning bac of the bowl 28 will raise thevalv 32 and permit outflow of thev shaving cream through the orifice 33and through the beveled sides 30 of the nozzle 29. The arrangementleaves a clear opening when the valve is raised and there 1s notresented such a discharge opening as wou d be clogged by the hardeningof the shaving cream. At the same time shaving cream extruded into thebowl 28 may be freely used with water as desired when the valve is againclosed by the screwing down of the bowl and said bowl may finally bewashed without danger of the moisture getting into the body of the creamin the cartridge' The disk 17 is formed with a hole or holes 18, therebeing a similar hole or holes in the bottom 11, in order that the userof the cup may observe the position of the piston 2i to therebyascertain'the approximate quantity of material remaining in thecartridge 22. The length of the screw 15 relatively to the cartridge 22is such that if the piston 24 should be advanced to a point to bearrested by the top 23 so that no further movement of the piston couldtake place in response to the turning of the screw, then a few threadsonly would be stripped from the nut 27 since the major portion of thethreads of the nut 27 will have passed beyond the screw. Thus, thestripping of the soft threads of the nut prevents damage to the deviceas a whole by an excessive turning of the screw.

The cylindrical body of the cartridge 22 is preferably formed of pa erlined with two layers of very thin tinfoil, the two layers insuring aperfect lining since the one .layer of tinfoil may have puncturesprofacture.

duced therein during the process of manu- The inner layer of tinfoil iscemented .to the wall of the cartridge and the two layers are cementedto each other. The cartridge is formed of a diameter to slip looselyinto-the body 10 and extended a proper length to clamp between the topand bottom of the casing when the top is screwed down. v

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not Thearrangement is such that the limit myself strictly to the mechanicaldetails herein illustrated, since manifestly the same can beconsiderably varied without departure from the spirit of the inventionas defined in the ap ended claims.

Having thus. escribed my invention, I claim as new, and desire to secureby Letters Patent:

1. A shaving cup includin a container adapted to hold a supply of saving cream, a nozzleon the container, a bowl on said container and towhich said nozzle discharges, and valve means controlling said nozzle toestablish or disestablish communication between the nozzle and bowl.

2. The combination with a container and a nozzle for the discharge ofthe material from the container, of a bowl ositioned to receive thematerial discharged by the nozzle and movable relatively to said nozzle,and valve means associated with said bowl and controlling said nozzle bythe relative movement of the bowl.

3. In a device of the class described employing a container, a nozzlefor the discharge of material from the container, a bowl positioned toreceive the material dis, charged by said nozzle, and a nozzle in thebowl and fitting on the first nozzle, the nozzle on the bowl havingsloping sides formed with outlets, and a valve on the nozzle of the bowlto close or open the first nozzle by turning movement of the bowl andits nozzle relatively to the first nozzle.

4. In a device of the class described, a container, a piston operatingtherein and having a central nut of soft metal rigid with said piston, ascrew extending axially in the container and through said pistonin'threaded engagement with the latter, and means to turn said screw foradvancing the piston, said screw terminating short of the end of thecontainer a distance to cause the plston to partially disengage itselffrom the threads of the screw when the piston has reached the end of thecontainer.

5. In a device of the class described, a container a removable cartridgetherein, a nozzle on said cartridge, a removable ca on the end of thecontainer through whic cap said nozzle extends, a bowl having a nozzlescrewing onto the first nozzle, valve means associated with the secondnozzle to close or open the'first nozzle, and means to cause dischargeof material from said car tridge through said nozzles.
